I was driving my car and as soon as i put the air on it started to run rough, i turned the air off and it continued. The first thing I did was give it a tune up and clean the IAC but no fix, I disconnected the Battery for a couple of hours and started to runs smooth. I was driving it a few days later and turned the air on and Bam same thing, instant rough running.I cleaned the IAC again, disconnected the battery, set the TPS sensor and cleaned and opened the pins on the salt and pepper shakers---no luck.... Please help with any suggestions.

check for a vaccum leak, such as the line for the HVAC that goes into the firewall by the evaporator lines
